Oh thank You very much for this very enlightening hint full of wisdom, Sir. Never thought about it, this completely changes everything! :O
The problem is, however, that it very often doesn't work this way. Yesterday i did some missions again, after an exploration trip which began as a hasty take off from the Gnosis [smile]. I wanted to get the system permit for Terra Mater and being still in my exploration fitted AspX, data delivery, surface scan and small cargo missions were the only missions i was really able to do. I didn't even try to get missions to the same destination, still it took me quite a few board flips to get 18 missions of this type. Obviously i could have get more cargo delivery missions, since you can now do those partially which is a really great improvement. (I haven't play the game for quite a long time) However, i explicitly didn't want to repeatedly return to Hecate since its not worth the time.
Additionally, you suggest that even if one takes missions to different destinations, one should normally still end up with a few missions per single destination, in fact around 3 per system in your example (which would be an acceptable ratio in my opinion). I ended up with 15 systems. Now 6/5 missions per system is pretty close to one if you ask me. So your example would be more appropriate as "Take 10 missions to 10 different systems A through J". And as i said, it already took board flips to get a sufficient number, such that i very probably could achieve my goal without repeatedly returning to my starting point.
Now you could obviously argue that my premise was wrong from the start, since i set a clear goal (getting allied with a local faction) i wanted to achieve in bounded time frame (one evening) without a general pupose ship. This obviously reduces my options by making all missions not offered by a single local faction and missions not fitting my ships criteria irrelevant. Leaving my personal opinion aside, that such arguments which mark a playstyle "wrong" are per se arrogant at best, Elite seems to encourage a roleplay type of playstyle. Thus, having the desire to support a single faction in a ship with a very narrow purpose is valid from the game perspective. Doing this in a tight time frame is a valid demand from the real life perspective. I once read a post on the forum written by a cmdr with something around 6500 ingame hours which is equivalent to around 4.5 hours a day every day from the game launch. Most people simply can't play that much but should also be able to achieve their goals. Now, i was able to get the system permit yesterday, although it took me much longer than i expected but it also remembered me of the awful mission system. Finally, without board flipping i certainly wouldn't be able to get the allied status in one evening and achieve this goal, which is very modest one considering such things as Fed/Empire rank, obtaining the vette or cutter, Shinrarta Dezhra access, Engineers, Powerplay etc.
Apologies for the sarcastic introduction btw, no insult intended.
